Wintering Birds on the Mystic: 10-11:30 a.m., Mystic Lakes Dam, 820 Mystic Valley Parkway, Medford. Free. For information: mystic02155@hotmail.com; http://www.fomr.org. Friends of the Mystic River and the Menotomy Bird Club will hold their annual Winter Bird Outing along the Mystic Lakes and the upper Mystic River to discover what birds might be found in the middle of winter. Each year hundreds of birds winter on and around the Mystic River and Lakes as long as open water is available. Led by Medford birding expert Paul M. Roberts, participants will look for raptors, such as Bald Eagle, Merlin, Cooper’s Hawk and Red-tailed Hawk; waterfowl, including Common and Hooded Mergansers; Red-bellied Woodpeckers; and more. The group will spend roughly an hour looking for raptors and waterfowl at the dam, and will then drive to the Fore Bay or along the river as conditions permit. There will be carpooling and walking only short distances from the cars. The event is scheduled to be 90 minutes long, but may be cut short if intensely cold. Dress appropriately for the weather. Bring binoculars and a birding field guide, if possible. Meet at the Mystic Lakes Dam. Park at the Medford Boat Club parking lot in Medford directly off the Mystic Valley Parkway. The parking lot is at the first left, about a half mile north of the Route 60 bridge crossing the Mystic; look for the white and blue “Medford Boat Club” sign at 860 Mystic Valley Parkway. The walk will be canceled in persistent rain, icy conditions, moderate snow fall, or if the parking lot is unplowed from previous substantial snowfall. The event will go in light snow flurries, as long as parking is open at the Mystic Lakes.

“Cinderella” by the Tanglewood Marionettes: 3 p.m., Mayer Campus Center, Room 203, Medford. Cost: $9, in advance; $10, at the door. Proceeds benefit the EPCS Scholarship Fund. For information and tickets: http://ase.tufts.edu/epcs/performance2018Cinderella.asp. Eliot-Pearson Children’s School at Tufts University will present “Cinderella” by the award-winning Tanglewood Marionettes. Set in the 18th-century and featuring a dozen lavishly costumed 30-inch marionettes, this production of “Cinderella” is a Tanglewood Marionettes showpiece. The story unfolds as the pages of a giant book open to reveal each painted setting — the village square, the rustic kitchen, the magnificent ballroom, plus many more. This telling is based on the original tale, but a few new surprises are in store: Cinderella’s method of conveyance to the ball is not the traditional coach-and-four, and, when all hope seems lost, a clever little bluebird saves the day for Cinderella.
